CROSS-REFERENCE TO RELATED APPLICATION(S)

This application claims priority to U.S. Provisional Patent Application Ser. No. 62/533,323, filed Jul. 17, 2017 and entitled, which is hereby incorporated herein by reference in its entirety.

FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

This invention was made with government support under Contract R44DK108689, awarded by the National Institute Of Diabetes And Digestive And Kidney Diseases of the National Institutes of Health. The government has certain rights in the invention.

TECHNICAL FIELD

The disclosed technology relates generally to preparing and/or shipping biological samples collected in any environment, and in particular, to the devices, methods, and design principles allowing the efficient preparation and shipping of bodily fluid samples.

BACKGROUND

The disclosure relates to apparatus, systems and methods for preparing and shipping bodily fluid samples collected in any environment, including non-clinical environments. While analysis laboratories are well suited to perform diagnostic tests, the collection of bodily fluid samples remains challenging, in particular for patients that do not have easy access to a suitable laboratory.

Devices, systems and methods to collect bodily fluids are necessary devices for the growing field of personalized medicine. As point-of-care devices continue to improve, an often overlooked area lies within the collection of samples from untrained users. Currently, biological samples are most commonly obtained via either simple-to-use methods or devices, as with generic lancing devices, or trained personnel, as with phlebotomy venipunctures. In order to transfer the bodily fluid to a container, receptacle, or an analysis device, multiple steps are required that are time consuming, error prone and/or cumbersome.

Patients without easy access can be located in rural areas, underserved urban and sub-urban areas, low resource areas, or generally do not have time or means to visit a laboratory, creating significant barriers to accessing diagnostic services. In order to reach patients in all locations, and connect them with suitable laboratories, robust systems for bodily fluid sample acquisition, stabilization, and shipping are required.

Thus, there is a need in the art for improved bodily fluid collection devices that can be self-applied at the convenience of the patient and utilize simple, cost-effective methods to handle bodily fluid samples, prepare and stabilize samples for transportation, and allow the robust transport to an analysis laboratory. More specifically, there is a need for simple and robust methods and devices to extract components of a blood sample, add reagents to the samples, and package the sample for safe and reliable transport. The disclosed methods and devices are simple to operate in any environment without additional equipment and/or any specific training.

Thus, there is a need in the art for improved apparatus, systems, and methods for bodily fluid sample preparation.

DETAILED DESCRIPTION

The various embodiments disclosed or contemplated herein relate to preparing biological specimens, such as blood, for shipment or transport. In various implementations, the sample preparation system is embodied as a centrifuge, using a motor to create a defined centrifugal force on the sample contained within the rotor in order to separate specimen components using gravity. When used in conjunction with a tube containing particular gels or reagents known in the art, the centrifuge separates the individual components of the sample, as would be well appreciated in the art.

It is understood that the various embodiments or devices, methods, and systems disclosed herein can be incorporated into or used with any other known medical devices, systems, and methods. For example, the various embodiments disclosed herein may be incorporated into or used with any of the medical devices and systems disclosed in co-pending U.S. Pat.

Turning to the drawings in greater detail, FIG. 1A and FIG. 1B depict exemplary implementations of the preparation and transportation/shipping device, or centrifuge system 10. According to the implementations of FIG. 1A and FIG. 1B, the centrifuge system 10 generally has a housing 12 containing a centrifuge frame 16 supporting a rotor 24, which are covered by a lid 20.

In these and other implementations, the rotor 24 has at least one opening 26 constructed and arranged to accept a biological sample (such as in a sample tube discussed below at 36) for centrifugation and transport. As such, it is understood that simple usability has been contemplated in the design to make the device and centrifuge system 10 as easy-to-operate as possible enabling use of the system 10 in the home, basic clinic, field, and/or retail settings.

It is understood that the rotor 24 contains the biological sample(s) and spins at a defined RPM to perform separation of subcomponents of a sample. As shown in the implementations of FIG. 2A and FIG. 2B, the rotor 24 can contain configurations that allow for either manual or automatic closing of a sealed compartment to house the biological sample after the user places the sample into the rotor 24.

In the implementations of FIG. 1A and FIG. 1B, the system 10 has a covering 18 on the rotor (FIG. 1A at 24) that can be removed to activate the centrifuge 16. In use according to other embodiments described in relation to FIG. 1C and FIG. 1D, the opening of the lid 20 can activate the centrifuge 16 without the covering. It is understood that enabling the automatic activation of the centrifuge 16 via the opening of the lid 20 and/or cover 18 would be achievable through a variety of structural configurations readily appreciated by those of skill in the art. In the implementations of FIG. 1A and FIG. 1B, the lid 20 has a tab 22.

According to these implementations, after a sample 26 is processed and is ready to be transported and/or shipped for analysis, the tab 22 can be affixed to the device housing 12 with adhesive 14 to prevent the centrifuge 16 from being re-opened. In various implementations, the adhesive 14 is single usage tape. It is understood that in other embodiments, the lid 22 can be closed with other methods or mechanisms known in the art.

The centrifuge system 10 according to these implementations has been constructed and arranged to meet or exceed the requirements of shipping and/or transporting biological samples, in particular to achieve a compact size, low cost, disposal of elements that may be contaminated by biological samples, and include all necessary components to meet the regulations of biological sample transportation set forth in UN Recommendation 3733 and International Air Transport Association Rule 3.6.2.

Continuing with the drawings, FIG. 1A shows an implementation of the centrifuge system 10 with the rotor 24, with the protective covering removed (shown in FIG. 1B at 18), such that the rotor 24 is exposed for sample insertion. In this implementation, the rotor 24 comprises an opening 26 that is constructed and arranged to accept the sample for centrifugation.

FIG. 1C and FIG. 1D depict an implementation of the system 10 having a detachable lid 20. In these implementations, the lid 20 is secured within the housing 12 when not in use, as would be understood. It is further understood that in various implementations, the housing 12 and lid 20 are foam or other thermodynamically favorable materials such as polystyrene (EPS).

As shown in the implementation of FIGS. 1C and 1D, the housing 12 contains a rotor 24 disposed within a cavity 24A at the base of the centrifuge frame 16. As described in relation to FIG. 1D, the centrifuge frame 16 contains openings 37, 39 for supporting various electronics such as PCBs 28, batteries 33, switches 19, 21 and a motor 25. In various implementations, the frame 16 is made of plastic or other light and rigid materials understood such as metals, polymers or composites.

In certain implementations, the lid 20 may serve as the only covering, whereas in alternate implementations like that of FIG. 1A and FIG. 1C, an additional covering 18 may be constructed and arranged to cover the centrifuge 16 and the rotor 24.

In the implementation of FIG. 1C, the cover 18 has a cover opening 18A. In use according to these implementations, the cover opening 18A is constructed and arranged to accommodate direct passage of a biological specimen into a rotor opening 26 which is in turn constructed and arranged to accept a biological specimen for centrifugation. FIG. 1C and FIG. 1D further show a counterbalance 26A disposed opposite the opening on the rotor, as would be understood by those of skill in the art.

In exemplary embodiments, the biological specimen can be in a container such as a HemoLink tube 36 from the user. In other embodiments, the rotor opening 26 is constructed and arranged to accept a tube in only one direction, ensuring correct processing of the sample. It is understood that many configurations are possible.

It is understood that these implementations of the cover opening 18A and rotor opening 26 are constructed and arranged so as to allow for the ease of use, that is, passage of the biological specimen into the rotor 24 for use. It will be appreciated that the cover 18 can be constructed from any number of materials, some non-limiting examples being plastic, Tyvek® and carboard.

As the centrifuge may be re-utilized it is beneficial to discard any part that may have come in contact with biological samples. A possible embodiment is to place the electronics and re-useable parts on a frame made of metal or hard plastic. The outer parts of the centrifuge can be made of easily discardable materials, such as cardboard. These parts would mostly be used to shield the electronics from sample spills as well as improve the usability of the device by hiding undesirable elements.

Various implementations of the system 10 are constructed and arranged to have automated actuation and safety stop features. In these implementations, the centrifugation process must be started only when the sample has been placed in the rotor without requiring the operation of any manual switch. In one embodiment a switch that is actuated when the lid is closed that can initiate the centrifugation process as well as operate as a safety switch. In these implementations, the switch must be protected from being actuated during shipping such that the centrifuge will only operate after the user places the sample in the rotor.

Continuing with the implementation of FIG. 1C, in this implementation a kill or locking switch 19 and activation switch 21 are provided. In these implementations, the locking switch 19 is constructed and arranged so as to prevent the operation of the centrifuge during transportation. In exemplary implementations, the locking switch 19 prevents activation of the centrifuge via a stored tube or tube cap (such as that described below in relation to FIG. 2C) in the locking switch 19 opening, as would be understood. In alternate implementations, the locking pin 19 can be activated/deactivated via an aligned pin that extends into an opening activating the locking switch 19 or other components and approaches understood in the art.

The lid is designed to interface with the frame and actuate switches to start or stop the process. The lid must have sufficient rigidity to avoid coming in contact with the spinning rotor. In use according to these implementations, when the user removes the tube 36 or tube cap from the locking switch 19 opening, the locking switch 19 is disabled. Subsequently, when the lid is returned to the closed position, the activation switch 21 is able to start the centrifuge 16, such as via a magnet disposed within the lid 20 that is constructed and arranged to activate the switch 21 and initiate centrifugation.

In the implementations, the switches 19, 21 are secured to the frame 16 and in operational communication with the rotor 24. That is, the rotor 24 is in operational communication with a motor 25 disposed within the housing 12, as well as with a printed circuit board (PCB) 28 via a PCB mount 29 and motor mount 31. In various implementations, the PCB 28 is constructed and arranged to operate and control of the timing and speed of the centrifuge rotor 24.

In various implementations, such as that of FIG. 1D, the centrifuge can be powered by a battery 33 and/or be plugged in to a power source.

Further, the PCB (or other microcontroller) 28 of these implementations is in operational communication with the switches 19, 21 and other electronic components such as memory, processors or other electronic devices known in the art. In exemplary implementations, they can be housed in a first cavity 37 defined within the frame.

Continuing with the switches 19, 21, in various implementations, the system 10 can be programmed such that the activation switch 21 initiates a timer on the PCB 28 or other control component to ensure that the sample has sufficient time to absorb reagent, clot, come to a specified temperature and/or meet some other condition or criteria understood by the skilled artisan.

That is, many different types of blood-related samples can be needed depending on the clinical analysis being performed. Typically, a centrifuge would have rotation speed controls and switches. In contrast, an aim of the shippable centrifuge system 10 is simplicity, and as such can be pre-programmed for execution of a specified assay, such as that which would be based on a prescription.

In various implementations, the PCB 28 or other microcontroller can be programmed to achieve a number of other objectives. For example, in order to ensure a quality sample upon reception, it is important to track the time at which the sample was acquired and the environment through which the sample was subjected. Accordingly, in certain implementations the PCB 28 or other microcontroller can be constructed and arranged to log time and temperature in order to reject samples that may have been subjected to out-of-specification conditions.

In various implementations of the system 10, the electronic components such as the PCB 28 are constructed and arranged to allow the system 10 to test the power supply to ensure sufficient voltage for operation. Because the rotor speed will vary depending on the voltage, it is important to have an internal test of the power supply onboard the shippable sample preparation system or as an included part of the system. If the power supply has insufficient voltage, an advantage of the system is that the power supply can be recharged or removed and replaced.

The electronic components also allow for several safety and consistency features. For example, redundant batteries or other power sources can be provided within the frame 16. That is a primary larger capacity battery 33 can be provided to power the rotor 24, and another smaller capacity battery disposed, for example, on the PCB 28 or elsewhere within the frame 16. This secondary battery (shown generally in the cavity at 37) can operate basic tasks with the onboard electronics/PCB 28. In certain implementations the larger capacity primary battery is a removable lithium ion battery or another battery with a larger capacity and density with a smaller footprint while the secondary battery is be a non-lithium ion battery to comply with shipping regulations.

Another safety feature within the device is to have a program or switch within the device that ensures the sample is only centrifuged at least and no more than one time. This means that if for some reason the centrifuge is interrupted mid-cycle, the centrifuge will be able to re-start to spin one time. If the device is opened after centrifugation is completed, it will not re-centrifuge the contents.

In other embodiments, the shippable sample preparation system 10 can contain wireless communication capabilities, such as but not limited to, NFC or Bluetooth® systems allowing for the transmission of data from the system to a user's smartphone device or a dedicated reader. In various implementations, these are disposed within the electronics housing 37 and in operational communication with the battery 33, PCB 28 and/or any other modules or processors and sensors necessary to perform the contemplated functions.

In certain implementations, the system 10 is constructed and arranged to record information about the sample processing, such as the activation time, the duration of the processing, the centrifugation speed, as well as the shipping conditions through time. In various implementations, a data storage device such as memory or a drive (not shown) are provided to store data. Additional information on the success of the centrifugation, geolocalization of the sample when the system was actuated and through time can be recorded from sensors (not shown) interconnected with the PCB and/or other components, such as GPS sensors and the like.

In various implementations, recorded data can be transmitted to the user or laboratory to assess quality metrics or other statistics about the patient or sample. Reversibly, information can be transmitted to the shippable sample preparation system via wired or wireless connections, thereby allowing the storage of the list of analytes that will be measured on the sample, which can replace or complement a laboratory requisition form, as well as the sample preparation parameters, such as centrifugation time, speed, and the like. It is understood that a further suite of known electronic components can be stored within the frame and placed into operational communication with the battery 33 and/or other electronic components so as to be constructed and arranged to effectuate the data collection and communication functions contemplated here.

As also shown in FIG. 1D, in these implementations a cavity 39 is disposed within the housing, which is constructed and arranged to hold a cooling element (FIG. 4B at 58), which is in thermodynamic communication with the rotor 24 and sample.

As shown in FIG. 2A, the rotor 24 of this implementation has a removable sample 32 constructed and arranged to fit within the opening 26. In this implementation, the rotor 24 connects to the motor (as shown in FIG. 1D at 25) in the housing (in FIG. 1A at 12) via an axle 30 disposed substantially at the center of the rotor 24.

In the implementation of FIG. 2B, the rotor 24 shows an implementation of the opening 26 constructed and arranged to accept a sample 32 housed in an optional additional removable container 34. It is understood that shipping liquid blood samples can require the use of a double-hulled container to prevent unwanted spillage. Certain implementations achieve this double-hulling by placing the sample 32 in a tube (primary container) 36 and having the secondary container 34 be a small container holding the tube, or the rotor 12 itself, or the box of the centrifuge. In various implementations, the secondary containment can be accomplished by having self-closing lids on the rotor actuated by the centrifugal forces or inertial forces that occur at the start or during centrifugation, as would be understood.

As shown in FIG. 2C, in certain implementations, the removable container 34 defines a lumen and contains a tube 36 disposed therein, the tube 36 defining a sample lumen 38. In these implementations, the container 34 can be removed for sample 32 insertion, and can integrate a tube cap 40 onto the lid 42 for forming a seal with the top of the tube 34. In these implementations, the removable container 34 can contain absorptive materials and/or reagents for addition to the sample tube 36.

In implementations such as that of FIG. 2D, the rotor 24 has a container 34 in the opening 26. The rotor 24 also has a lid 44 that automatically closes when the rotor starts to rotate, moving the tube opening 26 to a second location (shown on the right side at 46) so as to seal the tube area, as would be understood by the skilled artisan. In certain embodiments, the seal is hermetic or fluidic. Still in other embodiments, the described sealing can trigger a mechanical latch to hold the lid in a sealed position.

Turning to the implementation of FIG. 3A, a tube 36 having first 36A and second 36B elongate segments is shown. In this implementation, the segments 36A, 36B define internal lumens and are constructed and arranged to be fitted to one another, as would be understood, such that the second segment 36B serves as a “cap” to the first segment 36A, as shown by reference arrow A, and such that various components may be disposed within and fluids may flow therethrough.

In exemplary embodiments, the tube 36 comprises a gel 48 and a chemical reagent 50. In various implementations, the gel 48 can have thixotropic properties and become more liquid under shear, thus allowing the passage of certain bodily fluid components when the centrifugation occurs.

It is understood that in various implementations the chemical reagent 50 can be any of several reagents such as protease or nuclease inhibitors for preventing the degradation of proteins of RNA/DNA. The chemical reagent 50 may also contain various other known inhibitors, pHs, and/or salt concentrations that will prolong the preservation of the sample 32 as is known to an ordinary artisan. It is further understood that in use, the various components 48, 50, and a sample 32 can be disposed within the tube 36 so as to interact in a prescribed manner during centrifugation of the tube 36.

As shown in FIG. 3B, FIG. 3C and FIG. 3D, the rotor 24 has been fitted with a tube 36 that has a sample 32, a gel 48, and a chemical reagent 50 that is to be selectively applied to the sample 32. The first action of the centrifuge, shown in FIG. 3C, can be to use a first speed (reference arrow B) such as a slower speed, to separate the sample 32 into constituent parts 54. In various implementations, the sample 32 can be separated by or into the gel 48.

Following separation, as shown in FIG. 3D at reference arrow D, in some embodiments the centrifuge system 10 can also incorporate a shaking or vibration to mix the sample 32. In some embodiments, the chemical reagent 50 can be added before separation of components. In some embodiments, the gel 48 is not necessary in the tube. It is understood that many implementations are possible.

In the implementations of FIG. 4A and FIG. 4B, the centrifuge system 10 keeps the contents at a stables temperature. In these implementations, a phase-changing material 56, such as paraffin, that is constructed and arranged to keep the sample 32 at room temperature or buffer temperature spikes.

In another embodiment shown in FIG. 4B, a small cooling element 58 is disposed below or otherwise proximal to the centrifuge 16 so as to actively cool the sample 32 for room temperature or refrigerated shipping.

In addition to the aforementioned temperature control techniques, in various implementations of the centrifuge system 10 a temperature logging module is integrated into the electronics of the device, thereby allowing for the tracking of temperatures throughout the operation and shipping process described herein. Samples that have been subjected to out-of-specification conditions, either due to harsh conditions or a failure of the temperature control methods can thus be rejected.

In various implementations, the temperature history of a sample can be read wirelessly upon reception of the device and a decision to accept or reject the sample can be made based on that knowledge and the type of sample that was requested by the clinician.

FIG. 5A, FIG. 5B and FIG. 5C depict another embodiment of the centrifuge system 10. In these implementations, the centrifuge system 10 can be housed in a package that contains sub-units 60, 62. In use, by removing the outer sleeve 64 reveals the sub-units 60, 62 as well as a high-level instruction sheet 66. In one implementation, the first sub-unit 60 contains the sample collection unit as well as the materials required for sample collection.

The second sub-unit 62 contains a sample preparation and shipping unit. Once the sample is collected, it is placed in a receptacle in the second sub-unit 62. In these implementations, the sample preparation is actuated upon closing which can include centrifugation, time and temperature logging, refrigeration, tamper proofing, and recording to account for chain of custody.

In order to make the whole process achievable at home, the centrifuge is only one element of a larger kit. The centrifuge must be placed in a simple to understand workflow that the user can go through.
